ACNH Save Editor vs RPGMaker Save Editor

ACNH Save Editor is a free, open-source Nintendo Switch homebrew application for editing Animal Crossing: New Horizons saves. It changes Wallet Bells, Bank Bells, Nook Miles, house-loan values, and pocket items across the game’s save files. A searchable database contains more than 13,000 items, while Favorites presents 22 curated entries in a paginated alphabetical list. Pocket tools can clear a selected slot and save or load up to five loadouts on the SD card. Before each write, the editor makes a byte-verified SD-card backup; ZL can roll back to the latest backup. It recalculates hashes and checksums and repairs hashes after modifications. Edits are capped at in-game maximums and operate offline on-console. Version 1.4.0 edits only the primary resident, Villager0. Installation requires Atmosphère custom firmware and launching through Title Override or a forwarder, with SD-card and DBI/MTP packages provided.

RPGMaker Save Editor (RMSE) is a free, open-source tool for editing save files from RPG Maker MV and MZ. The application runs on Linux, macOS, and Windows, with a Node.js backend and Electron graphical interface. A save can be opened by dragging it from a file browser or choosing it in a file dialog. RMSE edits items, armor, and weapons, and lets users add inventory entries from a dropdown. Character edits are limited to characters in the active party. For values the app does not interpret, including data from custom plugins, users can export the save as raw JSON, make manual changes, and load it again. Before a save is overwritten, RMSE creates a backup and keeps the five newest copies in a `.rmse_backups` folder beside the save files. Save files themselves must stay inside the game directory; exported JSON can be stored anywhere. The project warns that edits to internal variables and switches can damage a save, so backups are advised. The repository has an Apache-2.0 license but no packaged releases. Documented setup requires cloning the repository, installing dependencies with npm, and running `npm start`. Support for older RPG Maker versions is not planned.
